. I, 'yd' pei wwwmain@ .septic-ation flied october 3 To all? whom it' may concern:

lie it known that l, Wimmer Wnsrsnnnl e citizen oi United States, residing at krnuigee, in the county oit Ulnnnlgee and State oi ldohoine, have invented newA and y,

Another object ot the invention is to pro- Vide'novel ineens :tor cooling the pot holding; ineens, to adapt the seine to edectuelly withstand the intense heetI 4Still another object of the invention is to provide e holding ineens for interchangeable use with either e single or o, double reversible pot.

Still another object of Vthe invention is to provide n double reversible pot, the pot sec tions oi' which are edopted to be assembled 4and disassembled with esse and 'lacility.v

" rersible pots Referring; new more particularly to the drawings, i designates e glass vdr'owing pot which, in the embodiment oi the invention shown in Figs. i., 2 and 3, is 'in the form ot o double pot, end in the embodiment oi the invention shown in Fig. 4, is in the form of o singie potn iln both structures the pots ore provided with. closed bottoms d," :ind seid pots ore mede ot l clay or other suitable highly reirectory'materiel.

"he donbie pot structure comprises two osed pot sections 3 and i errongged molt, or honing their bottoms 2 incontest end vtheir gloss receiving ,is or cavities ti i'ecing in opposite dipeeication of 'Letters Patent.

rections, one :facing downwardly or in i draining position, While the other-faces upwardly in operative position to receive the provided with interengeging connections,

in the forni oi ribs or projections 6 upon the bottoni of one section engaging; grooves or recesses 7 in the bottoni ofthe other sec tion, whereby seid pot sections are held in properelineinent sind from slipping laterelly upon one enother. The pot sections ire also formed in their outer Sides with spaced annuler grooves 8, one in each pot section, to receive correspondingly spaced ribs or projections 9 upon metallic heads or cloinps 10,. arranged at diametricelly opposite sides of the pot. 1

The heads or clamps 1Q form part-oi e. support whereby the pot is held end adept ed to be raised ind lowered, and special provision. is nitide for keeping said heads cool to adept them to withstand the intense heet to which they ogre subjected; To this end each "need is cored to form :i Water chamber ll with which' coininnnicittes e tibulor projection' l2, seid projection forniing e passage Jfor the inf-inw ci' cool Water to :ind the ontliow oi the heated Water from the Water ch einher.

Esch projection also serves es e spindie or trnnnion pivoteily mounting the pot in iii-shaped conducting; bearings 13, closed :it their onter ends 'by plugs or stuing boxes leend mounted upon the lower ends oi tubular supports i5. The tubular supports i serre es Water conductors or return pipes, ttor the 'dow ot' the heated Water troni the ohoinbers li to n suite/ble Weste or drain-j ontiet., Extending' through the pipes ere eo'oi "Wetter supply pipes 16 leading ironie suitable source of cold Water supply "and oomrnnniooting at their lower ends 'with thecliornbers il or couplings 13.

'it stili thus be seen. that provision is mede Jfor hoiding the pot sections assembled and pivote'ily mounting the some so that the pots may befreversed, enabling one (the upper) pot to be filled with glass for the drawing' ectionlwhile the other 'or lower pot is being -sulojeoted to the'hest oiv the furnace for the melting ond-drainage ont et the aftermath from,k the preceding drewing operation. .filso it' will be seen that the bends or clamps i0 Wiil absorb o portion oi? the bezit from the pot, thereby prolonging the iiii'e of the pot,

and that the cooling water flowing through the heads will also lreep the same comparatively cool and prevent them from rapidly disintegrating under the intense heat.

In practice, the pipes '15 are suitably heldA be reiaired or new )et sections` to be substituted therefor.

The above description ot the mode of mounting the pot also applies to the single pot structure shown in Fig. -L In the case ot' this` single pot structure, however, it will be understood that the pot is filled and the cylinder drawn, the pot reversed to melt and drain out the aftermath, and the pot IVhen turned back to normal position for a repetition of the lilling' and drawingoperations.

.Haring elaim:

1. A glass drawing pot comprising a pot body including superposed pot .sections each thus described my invention, I

having a bottom in engagement with the other section, clamping members disposed on opposite sides of said sections and retainingolubly receive the adjacent spindle in one end, a removable stuiiing box' in the other end of the passage, and fluidv .conducting pipes disposed in the other passage of the bearing, one of said pipes forming a support for said bearinga 2. A glass drawing pot comprising a pot body including"super-posed pot sections, the bottoms oli-which are in abutting relation and provided with interengaging 4ribs and grooves, clamping members arranged on opposite sides of said sections and having cooling chambers and hollow spindles pro- .jecting therefrom; bearings associated with said clamping members and having angular passages one el which receives the adjacent spindle whereby to revolubly mount said sections, luid'inlet pipes extending into the other passages of said. bearings, and fluid outlet pipes surrounding said inlet pipes and secured in said other passages whereby to form supports for the bearings.

In testin'lony whereof I ai'ix my signature.
